Interpretation of Development Plan for Slope Location (for Beginners)

Hello everyone,

we are beginners and about to purchase a hillside plot, south-facing slope (height difference north-south approx. 5 meters). The plot is located in Bavaria.

The supplement to the development plan foresees 2 full floors, but it must appear as a single story on the mountain side, while two stories may be visible on the valley side.

The following notes apply to this parcel:
1. Eaves side residential building mountain side 3.50 m from upper edge of finished floor CEILING
2. Upper edge of finished floor CEILING max. 516.03 m above sea level
3. The building may not have a basement.

The development plan or section looks as follows, but unfortunately we cannot quite understand the ground floor.

Does the ground floor therefore have to be completely underground, is that what is meant by the "yellow" area, or how is this to be interpreted?
For example, could the yellow area also be exposed so that the "ground floor" is flooded with light from three sides?

The building is not allowed to have a basement.

What is written about this in the justification?

The development plan or section looks as follows, but unfortunately we cannot fully explain the ground floor.

Without a legend, I can't either.
Please name the development plan (without linking!).

Hello,

about the legend:
the red dashed line is the current slope situation. The yellow area is the slope filling.

Regarding the filling, the development plan states:
The terrain must be filled up to at least 40 cm below the top of the finished floor level of the ground floor. Only natural stone retaining walls are permitted for this purpose. A height of 50 cm with a width of at least 100 cm is allowed. Terrain modifications are permitted as slopes up to a maximum inclination of 25° or in steps of max. The newly modeled terrain must lie within this area. The area of permissible fillings is shown and marked yellow in the system section for each parcel.

Here the question arises for us... From where is the 25 degrees measured?
If the terrain MUST be filled up to 40 cm below the top of the finished floor level of the ground floor, that is below the ground and thus contradicts the 25-degree slope? What is now a MUST, what is the minimum, what is the maximum of filling...

Our goal would be as little filling as possible so that as many windows as possible can be installed on the ground floor and thus create "normal living space."

Many thanks in advance for feedback!

In my eyes, there's no contradiction there. It's similar with my buddy; he’s only allowed to build 2 floors and has the south side ground floor and west side ground floor free. On the east side, the garage is directly adjacent, which also has a ground floor. I don't see any restriction in the development plan.

Does the ground floor therefore have to lie completely underground, is that what is meant by the "yellow" area, or how should that be interpreted?
For example, could one also expose the yellow area so that the "ground floor" is flooded with light from three sides?

Here the question already arises for us... From where are the 25 degrees applied?
If the terrain must be filled up to 40cm below the finished floor level of the ground floor, that is below ground and thus contradicts the inclination of 25 degrees? What is now a MUST, what is minimum, what is the maximum of the fill...

First of all, here is the legend for the sectional drawing:

and so that you have everything together, here is the section again:

and the text:

I read it this way: Within the yellow area you are allowed to shape the terrain. This is almost the entire property for you – only at the lower end of the slope does the yellow area end and the natural slope must be maintained.
The house itself must first be constructed with at least 40cm of fill up to the finished floor level. The shaping rather refers to the remaining terrain around it.
Where you start shaping or whether you shape at all is up to you. You just must not exceed the 25° slope or build retaining walls higher than 50cm (and those in natural stone – wow – that costs). Regarding the width, they have expressed themselves imprecisely here, in my opinion. I suspect what is meant is the depth of the step of 1m (but it could actually be the width -> ask).
Accordingly, you can calculate how much you can shape within your building window with retaining walls or a 25° slope.

With 25°, you overcome a height of 3m (approximately one story height) after about 6.4m. With the steps, you would reach this somewhat faster in about 5m (if the thing with width is correct). But it also depends on where your basement starts. Do you put it completely into the hill on the slope side, or do you perhaps raise it a bit? Your eaves may be 3.50m high (starting point is the contour line 516, which should roughly correspond to the street edge). Depending on the house depth and gravel (in both the literal and figurative sense ;)), your basement is also more than half exposed on the sides. (Unfortunately, I cannot read the depth of the building window anywhere here).

Leaving theory aside, this is a very nice plot but also a very expensive one to build on. You should expect more than 100K earthworks and slope support – I would rather estimate 130K. The natural stone walls are expensive.
